Hi everyone,

I am trying to implement a multi-step wizard (to import a BOM, one step for each line). I have therefore created an initial wizard, where you upload the BOM file and which processes it (this part works).

Then I wanted to create a wizard, which is responsible for processing each line. Ideally, a windows should pop-up for each line and present the user with the list of matched products and allow the user to select the correct one or create a new product. For this part, I have no clue how to achieve it. I tried to create a new wizard:

class bom_import_process(models.TransientModel):
    _name = 'bom_import_process'

    current_line = fields.Integer(string="Current line", required=True)
    product_id = fields.One2many('product.template', string="possible products")

Now, I want to populate the wizard with data, from the wizard that processed the BOM:

@api.multi
    def import_BOM(self):
     # BOM processing is done here
    new_record = self.env['bom_import_process'].create({
            'current_line': 0,
            'product_id': self._get_possible_product_matches(products[0]),
    })
    return {
            'name': _('Import line'),
            'type': 'ir.actions.act_window',
            'view_type': 'form',
            'view_mode': 'form',
            'res_model': 'bom_import_process',
            'res_id': new_record.id,
            'target': 'new',
        }

And this part does not work at all. It fails with an SQL query:

ProgrammingError: column bom_import_process.current_line does not exist

My guess is, that I am miss-using the wizard and writing data to it (which is something the user should do). Is there a way how I could accomplish what I want to do?

Thanks in advance,

Dan
